CAN oR Box HEAD CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 537,174, dated April 9,1 895; Application filed September 27, 1894'. Serial No. 524,243. (No odl.) Patented in Englandfebruary 22,1892, No. 3,407.

To all whom; it may concern.-

Be it known that I, RENVILLE ANSELL, a subject of the Queen of GreatBritain, residing at Croydon, in the county of Surrey, England, haveinvented new and useful Improvements in Can or Box Head CrimpingMachines, (the said invention having been partly covered by LettersPatent of Great Britain No. 3,407, dated February 22, 1892,) of whichthe following is a specification.

This invention relates to improvements in machinery or apparatus forrolling on the bottoms of tin boxes, cans, canisters and the likewhereby the said bottoms are attached to the bodies in abetter and morespeedy manner than hitherto by rendering the working of the machineautomatic as hereinafter more particularly described. I

In carrying out my invention on a suitable bed plate I mount twoheadstocks, the spine dle of the fixed headstock having a chuck or faceplate adapted to carry the flanged bottom of the box or thelike. ihespindle of the puppet head carries a spring or yielding gripping platefor the purpose hereinafter described and the puppet head is arranged to-be automatically moved forward and backward by means of a rack andtoothed segment operated from a pulley on the headstock spindle by a camdriven by a worm and worm wheel and suitable connecting rods and le- Thechuck or face plate is arranged to be revolved intermittently from thedriving pulley by means of a cone clutch adapted to engage with aconical recess in the pulley and working on a spline on the headstockspindle so that when the chuck has completed, say, two revolutions,sufficient to complete the rolling on operation, the clutch is put outof gear with the driving pulley.

The mechanism for operating the clutch comprises a cam arranged on theshaft of the aforesaid cam and adapted to move a spring lever connectedto the clutch so as to move the latter into gear with the drivingpulley,

the lever being held in this position by a spring catch, the clutchbeing moved out of gear by means of a cam operated from the headstockspindle by spiral gearing, which cam impinges against a tooth orprojection on the spring catch and releases the lever.

In order'that the chuckor face plate shall stop when the clutch is putout of gear with the driving pulley I provide the clutch with a conicalrecess designed to engage a fixed cone.

Above the chuck or face plate is arranged what I term a rolling on platethe edge of the said plate being shaped to-correspond with the edge ofthe chuck or face plate. The said rolling on plate is carried by acrosshead sliding upon uprights fixed to the bed plate and springs areplaced between the under side of thesaid crosshead and the bed plate andbetween the upper side of the crosshead and another crosshead sliding onthe said uprights and connected by rods to a lever operated by the camfirst referred to.

To enable my invention to be fully understood I will describe how it canbe carried into practice by reference to the accompanying. drawings, inwhich Figure 1 is a side elevation of my improved machinefor rolling onthe bottoms of tin boxes, cans, canisters and the like. Fig. 2 is an endelevation of the same. Fig. 3 is an elevation ofa part of the machinelooking from the opposite side to that shown in Fig. 1. 'Fig. 4 is aplan of the machine partly in section. Fig. 5 is a longitudinal sectionshow-- ing clearly the driving spindle and parts connect'ed therewith.Fig. 6 is a sectional elevation of part of the machine drawn to anenlarged scale showing a box in position for being operated upon, thedevices'for holding and rotating the box and the rolling-on plate.

to is a shaft arranged at the lower part of the bench b and carrying apulley to, de' 9 Fig. 3 is the cam for communicating the signed to drivethe pulley i, and fast and loose pulleys 20 10 Assuming theiparts'of themachine to be in the position indicated in the drawings, that is to say,the clutch j disengaged from the ,pulley 2' so that the chuck d isstationary, the puppet head e in its extreme outward position and therolling on plate q in its highest position then the machine beingstarted the operation is as follows: The bottom a: of the box (the edge*of which is, as shown in Fig.6, doubled or folded outwardto form a 3trough y to receive the edge of the bottom end of the box as usual')is;placed upon the chuck or face plate cl and the edge of the bottom endof the box is held in the said trough y, th'e lid etbeing first placedupon the box. The cam g in moving in thedirection of the arrow Fig. 3will cause the frameh to move upward and move forward thepuppet head eso as to press the gripping iplate f against the lid 2 of the boxand-maintain the edge of the bottom end of the box in the trough y inthe bottom w'the pressure of the gripping platef being limited by thespring f The rolling onWplateqwillat the same time be moved downwardagainst theiprcssure of the springs 9""(through thedownward movement ofthe cross-head s compressing the springs r so as to bring itsedgeiagainst the turned upzportion of the box bottom and the clutchjwill be put in gear with the pulleyit' by-reason oflthe cam. Yoimpingingagainst the plate Z on the lever 1 whereby the spindle cwill be revolvedand rotatethe box, the two sides of the troughed portion of the bottoma; being pressed by theaction of-the rolling on plate q and the chuckorfaceplate (Z against the edge of the bottom end of the box so as tosecurely fix on the bottom and make a good and tight joint as shownbythe sectional view of the box in Fig. 7. The clutchj is held in gearwith the ;pulley 6 while 'the chuck orface plated makes a certainnumberof revolutions (innpractico Ifind two revolutions to be suflicient)thisbeing effected bythe spring catch m engagingwith the end ofthelever1 when depressed byithe cam 70 the camn first moving-out of the-way ofthetoothn'on thespringcatch. When thetwo revolutions of the chuck d areeffected the cam n impinges againstthetooth n and forces back thecatchan whereby the leverl moves up under the action of the springl and putsthe olutchj out of gear with the pulley tithe recess in-the clutclnatthefsame time-engag ing with theconeip' and stopping the chuck tl. Thecamg thenmoves down the frameh thereby moving back thepuppet head e toits normal position and releasing the box and lifting the rods 15, 23whereby the collars t, t liftthe cross-head q carrying the rolling onplate into its normal position. The use of the springs 0" enables therolling on plate to yield or accommodate itself to square, oval or othershaped boxes or the like.

By the employment of a cam such as g and the arrangement of the cam is,the lever l, catch m and cam n the continued rotation of the pulleytproduces an automatic intermittent action of the puppet head e,crosshead q and chuck or face plate (1, that is to say, an interval oftime elapses between the two former being moved back into their normalpositions and again being moved forward to their operative positions andbetween each two revolutions of the latter, this interval allowinganother box and bottom to be placed in position, the machine againoperating as before and so on.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat-I claim is- 1 In a can'making machine the combination with thegripping plate, of the chuck and its spindle, a loose pulley mountedonsaid spindle,a clutch for operatively connecting the pulley andspindle and means for locking the clutch and spindle for joint movement,substantially as described.

2. In a can making machine the combination with the gripping plate, ofthe chuck and its spindle, a loose pulley mounted on said spindle, aclutch for operatively connecting said pulley and spindle, means forlocking the clutch and spindle for joint movement and a device operatedby the spindle for releasing said locking means, substantially asdescribed.

3. In a can making machine the combination with the gripping plate, ofthe revolving sta tionary chuck and its spindle, a pulley looselymounted on said spindle, a clutch for coupling the spindle and pulleyand means operatively connected with said pulley for forcing the clutchinto engagement therewith, substantially as described.
